I thank the noble Lord for that intervention. I have been in practice for very many years and I still am. One of the things that always struck me was how wrong I was about trying to predict when a patient would die. I well remember a typical case of a lady who was only 28. She had inoperable cancer of her throat. She was in great distress, with pain and distressed breathing. I saw my job as a doctor to relieve all her symptoms, whatever the cost. I said to her, “If you like, I can put a needle into your vein and titrate you with heroin”. Heroin is a marvellous drug. You have to dilute it in a large volume and not use the small volumes in the ampoule, because if a gun goes off you might suddenly give them too much too quickly. I titrated her and asked her to tell me when all the symptoms had gone.
Eventually she said, “Yes, that’s fine”. It was a huge dose of heroin. I had no problem about giving it. The strange thing was, not only did it not kill her, it gave her a new lease of life. It is unrelieved pain that is the killer.
